Chevy Silverado: Problems & Solutions



  • jlandjland Posts: 3
    2000 Silverado, 5.3L, 106,000 mi. Same thing happening here in the past month or so. Coolant leaking on track rod and drips on L. front side of engine. Am looking for any new posts about the root cause. Some stains, like leaks, behind the water pump but dry when inspected. Will have to check right after motor has run for a few miles. Water pump would be the usual suspect. Have used up a gallon of antifreeze topping the system but very little fluid shows in the driveway here. Slow oil leak started about the same time as the coolant leak. Front main seal is OK and oil may be just a coincidence.

    As you may have noticed, we are reorganizing the Forums to allow better focus and easier searching when you have a particular problem or comment about any given vehicle. Many of the large generic discussions (like this one) will be closed to new posts, and we ask that you continue in the more focused discussions that you can find at the Group page for the vehicle, linked below. This discussion will not be deleted, so you can still search for information in it.

    We recognize this is going to take some getting used to (for the hosts too!), so please bear with us. If you have any questions, you can always email the host of any discussion - the link is at the top of each page to the host who oversees that discussion.

    If you don't see a discussion in the group appropriate to your question or comment, start a new one, or send me an email, and I'll point you in the right direction!

    It could be a fuel pump... can you hear the "chevy" fuel pump whine when you turn the key on? It could be that until the fuel pump gets warmed up it doesn't want to work right. Usually a non starting issue is only a couple of things... spark but no fuel, or fuel but no spark. It sounds like you have done everything about the spark issue... unless the computer is fouled up or the ill-timed, but if it runs fine once started, I would lean more towards the fuel supply not being there.

    Try this... take off the air cleaner housing and dump a small amount of fuel into the injector assembly just like in the old days of carbed vehicles. See if the truck fires up. It shouldn't take much - you don't want to flood it. I would think (I may be talking out my butt here but...) that if the truck fires right up than it could be the fuel pump.

    I am sure that dumping gas down the fuel injector assembly should work as I one time helped a couple of people stranded in a late 90's model Chevy with a 5.7 that had a fuel pump fail. They were limping along pouring gas down the fuel injector assembly and driving till the truck ran out of gas. Then they would repeat and keep going. I towed them to a shop in town (they still had 30 miles to go!). The 4.3 even in 2000 is not much different than the late 90's 5.7. It's just missing a couple of cylinders.

    I'm a little late replying to this post,but I don't see any replies so here's my 2 cents worth.... It sounds like maybe you have a clogged fuel filter. Change the filter and see what happens.

    like previously mentioned, the owners manual will tell you how to fix the change oil light, but the check engine light is not related to the oil change. The dealer will probably charge you an hour's worth of labor to check the code as will and individual shop, unless of course you have a good mechanic that you know and trust. Then he might not charge you for a 10 second check and reset of the computer. I might suggest heading to Autozone or calling the parts houses in your town. I'll bet one of them will have the ability to check the code and generally at no cost.
